So I got duck eggs from someone to hatch, she is taking any that hatch back. But as I was putting them in the incubator there were these tiny white eggs, 33-42G, then 2 colored eggs that I know are chicken eggs. I set the duck eggs but held these out to set after a week so they hatch at the same time. But if they are tiny duck eggs from new layers I don't want to set them. And I can't tell. The bigger one I am almost pos is a chicken egg.
